This article mainly introduces the java parameter garbled how to do, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

For data submitted in Post mode, you can use request.setCharacterEncoding ("gb2312"); to explicitly specify the encoding to be used when getting request parameters. However, this method is only valid for Post submission.

Request.setCharacterEncoding ("gb2312"); the reason why the GET submission is invalid is that the code only sets the encoding of the request entity, and the data submitted by GET is the [resource name? param1= "Zhang San" & param2=123] stored in the request line, so the GET request method is invalid.

For the data submitted by Get, the garbled code can only be resolved manually:

String newName=newString (name.getBytes ("ISO8859-1"), "gb2312"); String user=newString (request.getParameter ("user") .getBytes ("ISO-8859-1"), "UTF-8")

Of course, this method is also effective for the Post approach.

The URIEncoding of the http connector can be configured in the server.xml of tomcat to specify the encoding that the server uses by default when getting the request parameters.

The following statements are usually used in servlet to solve the problem of Chinese garbled code:

Request.setCharacterEncoding () is to set the value taken from the request or fetched from the database.

The purpose of response.setContentType () is to control the behavior of the browser, that is, to control the browser to decode with the specified encoding (specifying the encoding of the HTTP response, as well as the encoding displayed by the browser).

The purpose of response.setCharacterEncoding () is for garbled strings output by response.getWriter (); this solution is not needed in the case of response.getOutputStream (), because this sentence is meant to decode the data in the response object in UTF-8 and send it to the browser.

Response.getOutputStream (). Write ("Chinese" .getBytes ()) outputs data, which is a byte stream that uses whatever encoding is used to write to memory.
